Waterjet vs. Oscillating Knife Systems: The Best Way to Cut Ejection Rubber in Die Making

When it comes to die making, precision and efficiency aren’t optional—they’re business-critical. Cutting ejection rubber is no exception. For years, waterjet systems were the go-to—but the game has changed. Today, more die makers are choosing oscillating knife systems—and for good reason.

Let’s break down the key differences and explain why the Serviform RubbA stands out.

Waterjet Cutting: Powerful—but Problematic

Waterjets slice rubber using high-pressure . While effective, they come with serious downsides:

• High Operating Costs: Requires water, power, and abrasives like garnet—costs that add up fast.
  
• Maintenance-Heavy: Pumps, nozzles, seals, and filters wear out quickly under pressure and grit.
  
• Mess and Cleanup: Creates slurry that demands extensive cleanup and water management.
  
• Large Footprint: Needs space and infrastructure—less ideal for small to midsize shops.
  

Oscillating Knife: Clean, Controlled, Cost-Effective

Oscillating knife systems use a high-speed vibrating blade to cut rubber cleanly—no water, no mess:

• Lower Maintenance: Quick, cheap blade changes—no abrasive wear.
  
• Clean Operation: No slurry means no cleanup or plumbing complexity.
  
• Precision & Speed: Great for intricate designs, variable thicknesses, and tight tolerances.
  
• Compact Footprint: Fits easily in die shops without modification.

Why the Serviform RubbA Leads the Pack
